On those suicide statistics: The high percentages trans activists use are based on very small samples in surveys carried out by LGBTQetc. organisations and have to do with suicidal ideation and self-reported attempts to commit suicide. They do not refer to completed suicides.
What we lack is good data on completed suicides by young trans-identifying people, the kind of data which also takes into account existing comorbidities, such as various mental health conditions, and the kinds of factors which contribute towards suicide, such as discrimination against gay and Lesbian people.
The reason we need all that data is because suicide rates are (tragically) also higher among those young people who are gay or Lesbian and (equally tragically) higher among young people who suffer from anxiety, depression and various other mental disorders.
Because many of those things can be true simultaneously for someone, the question if trans-identifying young people are more likely to commit suicide can't be separated easily from the increased suicide rates for those who are gay or Lesbian i a hostile environment and for those who suffer from various mental disorders.
This is what I found about the completed suicide rate among young trans-identifying people:
A recent study of three major youth clinics concluded that suicidality of trans-identifying teens is only somewhat elevated compared to that of youth referred for mental health issues unrelated to gender identity struggles (de Graaf et al., 2020). Another study found that transgender-identifying teens have relatively similar rates of suicidality compared to teens who are gay, lesbian and bisexual (Toomey, Syvertsen, & Shramko, 2018). Depression, eating disorders, autism spectrum conditions, and other mental health conditions commonly found in transgender-identifying youth (Kaltiala-Heino, Bergman, Työläjärvi, & Frisen, 2018; Kozlowska, McClure, et al., 2021; Morandini, Kelly, de Graaf, Carmichael, & Dar-Nimrod, 2021) are all known to independently contribute to the probability of suicide (Biggs, 2022; Simon & VonKorff, 1998; Smith, Zuromski, & Dodd, 2018).
